RF3600E - 10/21/09 ? ideal front-end filter for european wireless receivers low-loss, coupled-resonator quartz design simple external impedance matching complies with directive 2002/95/ec (rohs) the RF3600E is a low-loss, compact, and economical surface-acoustic-wave (saw) filter designed to pro- vide front-end selectivity in 868.6 mhz receivers. receiver designs using this filter include superheterodyne with 10.7 mhz or lower intermediate frequencies, plus direct conversion and superregeneratives. typical applications of these receivers are wireless remote-control and security devices operating in europe under etsi i-ets 300 220. 868.60 mhz saw filter RF3600E caution: electrostatic sensitive device. observe precautions for handling. notes: 1. unless noted otherwise, all measurements are made with the filter installed in the specified test fixture which is connected to a 50 ? test system with vswr 1.2:1. the test fixture l and c are adjusted for minimum insertion loss at the filter center frequency, f c . note that insertion loss and bandwidth and passband shape are dependent on the impedance matching component values and quality. 2. the frequency f c is defined as the midpoint between the 3db frequencies. 3. where noted specifications apply over the entire specified operating temperature range of -40 to 90c. 4. the turnover temperature, t o , is the temperature of maximum (or turnover) frequency, f o . the nominal frequency at any case temperature, t c , may be calculated from: f=f o [1 - ftc (t o -t c ) 2 ]. 5. frequency aging is the change in fc with time and is specified at +65 c or less. aging may exceed the specification for prol onged temperatures above +65 c. typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years. 6. the design, manufacturing process, and specifications of this device are subject to change. 7. one or more of the following u.s. patents apply: 4,54,488, 4,616,197, and others pending. 8. all equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sa le. 9. tape and reel standard for ansi / eia 481. sm3030-8 case 3.0 x 3.0 pb characteristic sym notes minimum typical maximum units center frequency @ 25c f c 1, 2, 3 868.60 mhz insertion loss il 1, 3 1.8 2.3 db 3 db bandwidth bw 3 1, 2, 3 1600 2100 khz passband ripple, 868 to 870 mhz 0.8 1.5 db p-p attenuation: (relative to il min ) 10 to 800 mhz 1, 3 47 50 db 800 to 858 mhz 32 35 858 to 862 mhz 25 28 862 to 864 mhz 17 20 872 to 876 mhz 19 22 876 to 888 mhz 15 18 888 to 890 mhz 32 35 902 to 1000 mhz 35 38 temperature freq. temp. coefficient ftc 3, 4 0.032 ppm/c 2 frequency aging absolute value during the first year |fa| 5 <10 ppm/yr impedance @ f c input z in = r in || c in z in 1 4.7 k ? || 1.57 pf output z out = r out || c out z out 3.8 k ? || 1.74 pf lid symbolization (in addition to lot and/or date codes) 816 // ywws standard reel quantity reel size 7 inch 9 500 pieces/reel reel size 13 inch 3000 pieces/reel
